Title: Oil separator for evaporator
Inventor: LEE SUNG-TAE
IPC: F25B43/02
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To effectually separate oil in a refrigerant by providing a refrigerant outflow port through which the refrigerant flows out upward toward an evaporator inflow hole and an oil outflow port through which oil is flowed downward between an inflow port to which the refrigerant containing the oil is guided and the inflow hole of the evaporator. SOLUTION: A refrigerant in a liquid state flowed after passage through a capillary tube 5 is flowed into a inflow port 11 of an oil separation apparatus 40 and is simultaneously evaporated. Since the inner diameter of an oil guiding pipe 19 of the oil separation apparatus 40 is smaller than that of a refrigerant outflow port 21, the evaporated refrigerant flows upward and most part thereof is supplied to an evaporator 7 after passage through the refrigerant outflow port 21. The oil in the refrigerant flowed into the inflow port 11 from the capillary tube 5 is prevented from being evaporated, it is separated from the refrigerant, and the separated oil 25 is flowed out after passage through the oil guiding pipe 19. The oil 25 directed upward along a pipe wall of the refrigerant outflow port 21 owing to an air stream is collected by a stopping step 16, and is thereafter flowed downward.

Title: Image forming device
Inventor: IKESUE TATSUYA
IPC: G03G15/045
Filed: 1989-06-07
Abstract: PURPOSE:To obtain a clear image without generating the uneveness of density and fogging even when the image is formed on larger-sized sheet by varying inflow current to a main electrostatically charging device for a fixed period with the size change of an image carrier. CONSTITUTION:The subject device is provided with a power source 16, which impresses negative direct current on the main electrostatically charging device 14, and a controller 17, which varies the inflow current to the main electrostatically charging device 14 with the power source 16 for the fixed period by changing the size of the image carrier 10. Thus, continuous copying is performed by means of the photosensitive body 10 composed of a negative organic photoconductive body 12 and a part of the photosensitive body 10 is directly charged with positive charges by a transfer charge 21 depending on the size of the sheet in the case of transfer. And even when the photosensitive body 10 is positively electrostatically charged, after the continuous copying is completed, the inflow current to the main electrostatically charging device 14 is increased compared with the normal time when the subsequent copying is started and the photosensitive body 10 is highly electrostatically charged as a whole. Thus, even when the subsequent image forming process is performed with the larger-sized sheet, the uneveness of the density and the fogging are dissolved and the clear excellent image is obtained.

IPC: G01R31/10
Filed: 1986-06-20
Abstract: PURPOSE:To easily locate the position of a trouble point even in the case of complicated systematic constitution, by superposing a voltage pulse to DC voltage to again subject the trouble point to dielectric breakdown and measuring the time before said DC voltage begins to drop. CONSTITUTION:When the dielectric strength of a trouble point is calculated, a distributing system is charged with DC voltage slightly smaller than said dielectric strength.

Said pulse like voltage advances on the distribution line 4 toward branch points and again returns to the resistor R2 of the pulse generating means 11 while is reflected and transmitted at each branch point. The wave form of this returned voltage is measured by a voltage measuring means 12. When the time from the point of time when a voltage pulse is applied to the point of time when DC voltage begins to drop is measured, the distance reaching the trouble point along the power distribution line is calculated from the means 11.
